MineReduce-based Multi-Start ILS (MR-MS-ILS)

This repository stores the source code of the MineReduce-based Multi-Start Iterated Local Search solver used for the MESS-2020+1 competition.

Dependencies

This solver uses FPmax* LIB.

You should download and build it before compiling the solver (see instructions on the link above).

Compiling the solver

1. Create a directory named "include" in this project's base directory:
   mkdir include
2. Copy the required FPmax* LIB header files into include.
3. Copy the FPmax* LIB shared library (.so on Linux or .dll on Windows) into this project's base directory.
4. Compile the solver with make.

Running the solver

./mrils <input_file> <solution_file> <timeout> <random_seed>

For example, the command line:

./mrils ../Instances/Public/wlp18.dzn sol18.txt 200 0

Runs for 200s the solver on instance wlp18.dzn stored in the directory ../Instances/Public/ and delivers the solution in the file sol18.txt.
